Abstract
La presente se refiere a procesos para epimerizar alcoholes de compuestos que tienen un sustituyente hidroxilo en un carbono alílico asimétrico, tales como compuestos utiles para la síntesis de análogos de la vitamina D en donde el sustituyente hidroxilo epimérico está en la posicion 24. La presente se refiere además a métodos para producir productos intermedios utiles para la síntesis de calcipotriol por medio de dichos procesos de epimerizacion. Reivindicacion 1: Un método para epimerizar un epímero o mezcla epimérica de un compuesto que comprende una cadena lateral de estructura general A y/o B, en la pocsicion del átomo de carbono al que se unen el grupo hidroxi y R3; poniendo en contacto dicho epímero o mezcla epimérica con un ácido en presencia de agua; en donde R3 es alquilo, alquenilo, alquinilo o cicloalquilo, opcionalmente sustituido con uno o más sustituyentes seleccionados del grupo que consiste en alquilo, alcoxicarbonilo, halogeno, hidroxi, metoxi y etoxi; en donde el carbono marcado con un asterisco está unido con un enlace simple al átomo de carbono C-17 de un fragmento de un análogo de la vitamina D; o en donde el carbono marcado con un asterisco está unido con un enlace simple a un fragmento de un precursor para la síntesis de un análogo de la vitamina D en su posicion análoga C-17.This refers to processes for epimerizing alcohols of compounds having a hydroxyl substituent on an asymmetric allyl carbon, such as compounds useful for the synthesis of analogs of vitamin D wherein the epimeric hydroxyl substituent is at position 24. The present is it also refers to methods for producing useful intermediates for the synthesis of calcipotriol by means of said epimerization processes. Claim 1: A method for epimerizing an epimer or epimeric mixture of a compound comprising a side chain of general structure A and / or B, in the position of the carbon atom to which the hydroxy group and R3 are attached; contacting said epimer or epimeric mixture with an acid in the presence of water; wherein R3 is alkyl, alkenyl, alkynyl or cycloalkyl, optionally substituted with one or more substituents selected from the group consisting of alkyl, alkoxycarbonyl, halogen, hydroxy, methoxy and ethoxy; wherein the carbon marked with an asterisk is attached with a single bond to the C-17 carbon atom of a fragment of a vitamin D analog; or wherein the carbon marked with an asterisk is attached with a single bond to a fragment of a precursor for the synthesis of a vitamin D analog in its analogous position C-17.
